This is an ISO that's built for a salvaged filesystem of a build of Feren OS that dates back to the final months of 2015, from the time when Feren OS 2016.0 was in development. Feren OS 2015.3 was later released as "Feren OS 2016.0" due to development times lasting until 2016.
Since this build only had its filesystem remaining, the latest Feren OS ISOs had to be used to provide a means of booting into this build. Furthermore, you may experience some oddities with permissions being incorrect on certain files due to this build having been found with incorrect file ownership. A once-over with the latest Feren OS Classic's permissions was done to the permissions of this build's filesystem, but issues may still occur.
The boot screen used in the Live Session is also inaccurate to the original source material, and the kernel had to be regenerated, as the files used in the live session are from the filesystem itself, after regenerating the kernel files, to provide the best experience when booting into this (rather than using the latest Feren OS Classic's kernel files for the live session).
Finally, you'll need to do a few tweaks to get to a Live Session Desktop while you're in the Live Session. When in the black void that is the Live Session by default do the following:
1. Enter TTY2 via CTRL+ALT+F2
2. Log in as 'feren' with no password
3. Type 'sudo nano /etc/lightdm/lightdm.conf'
4. Add this line to the end of it, followed by CTRL+X and Y to save and exit: 'user-session=cinnamon'
5. Finally run 'systemctl restart lightdm' to start the Live Session properly.
Random Fact: This build contains Web Browser Manager, which would later debut in Feren OS 2016.1 if I recall correctly, however it immediately crashes in this build due to missing its icon.
